Hi Mike,
Thanks for all the info on the MIDI spec.

Right now I'm primarily trying to confirm if I have the most appropriate settings in my BiaB MIDI/Audio Driver setup. (You can see my settings above.) With my current settings I get the MIDI sounds coming out of my RD-800 and the Real Tracks coming out of the PC.

It seems like the only way to get the MIDI sounds from my RD-800 is to uncheck Use VSTi/DXi Synth. If it's true that I must uncheck Use VSTi/DXi Synth then does it matter what I select under Synthesizer / Sound Card, or what is selected under GM2 support (128 extra patches). If those 2 settings are irrelevant when Use VSTi/DXi Synth is unchecked, then why are they even selectable? If those 2 settings DO make a difference, then what would be good choices? Also, what makes the most sense under Driver Type (WAS, MME, ASIO)?

Hope this question makes sense. Thanks again for humoring a newbie.
